Staff was very friendly, fitness facilities were top of the line, food was consistently awesome

The title hotel does not do the Grand Mercure justice!!! The accommodations were over the top. The breakfast buffet was always amazing. Happy hour in the evenings were well worth the price. The room was spacious and very nicely appointed. The location in relationship to the malls was great. I would be honored to stay here again.

Fantastic location with a top notch staff that is keen to accommodate your every need.

We stayed 2.5 months upon arrival in S. Korea and before moving to our new home. We enjoyed our stay. Had we known earlier we would stay so long, we would have taken a 3rd bedroom (our 2 kids did share 1 bedroom) and insisted on being placed at higher floor with a view away from the construction site. Service was impeccable, especially from the concierge.

I stayed at the 1 bedroom suite (superior suite) for 1 month. The staff are warm and attentive, the hotel is close to IPARK mall & Yongsan station, the room is spacious and well cared for. Overall it was a very satisfactory experience. Definitely will visit again.

3 months stay at a serviced apartment Nd the service was relentlessly warm and caring.

As always, it was a pleasant time in Grand Mercure Yongsan.

Everything was excellent: the breakfast, the room, the hotel personnel, etc.

Very nice, the staff is extremely friendly.

The front desk staff were wonderful and offered good advice about restaurants. The room was spacious and very clean. The only thing that would have been convenient was to have more than two sets of cutlery and dishes since there were three of us. Other than that, it was a great stay!

It has the best facilities in Korea and a kind check-in counter. All the facilities are clean, and the night view outside the hotel also has the best view. Also, the train station and the movie theater are connected, so it has an excellent location. Despite its excellent accessibility, it is well positioned to take a quiet rest.

From check-in to check-out, complete and meticulous service, well-appointed rooms and excellent interiors, meticulous amenities and a kitchen without deficiencies were the best. I especially liked the bluetooth speaker. The bedding was also very comfortable. After waking up, I was so cozy and happy to drink Nespresso coffee while watching the snow fluttering outside the window.

It's my first time visiting. I went to the anniversary and it was so nice. The service was good, the room condition was good, and it was very good. I have a doctor to visit again. It's well-positioned and has a clean table.

I have stayed at the hotel several times now and can probably notice the small things slightly better than new customers. Usually, the stays are above par and pretty satisfying. And this time as well, overall I enjoyed the visit. However, there were a few things that could have gone a little more smoothly: 1.) Check-in Procedures: The check-in lady asked for my spouse's ID. In all my previous stays at this hotel, this was never asked for before. Although it's fine I have to grab this, but if you're going to change / introduce a new policy, the lady should have more clearly explained the reason for the change in policy. 2.) Check-in Procedures: The check-in lady forgot to ask for my vehicle's license plate number. I had parked my car in the garage earlier, and when I had tried to leave the garage after the check-in, the gate did not recognize my vehicle. It caused confusion with the gatekeeper on the audio call button, and there were cars backed up behind me because of the delay. Very inconvenient. 3.) Check-in Procedures: The check-in lady only provided 2 card keys instead of the usual 3. I was not able to provide a card key for my spouse since 1 card was inserted to charge the power in the room and 1 card was with me. 4.) Check-in Procedures: After completion of the check-in and everything was complete, we started to collect our bags and headed towards the elevator. The check-in lady called us back to the counter because she forgot to charge the deposit fee for the room. She should have completed that transaction while I was still sitting at the check-in counter. Very unprofessional, and the lack of training is clearly apparent. 5.) Room cleanliness: There was a pet stain (cat?) behind the door that the cleaning lady missed from the previous customer. I tried to wipe some of it, but the odor was so strong we had to ask the front desk to send the cleaning lady and use the cleaning solution and deodorizer. The stench of that urine was so awful, I will always remember that as part of my hotel stay. 6.) Breakfast staff: The staff that was working on the floor was playing on her iPhone. Again, really not a big deal for cheaper hotels, but for higher service hotels, the customers are not paying expensive hotel prices to watch the staff playing on their phone. 7.) Breakfast staff: The staff is usually supposed to ask the customers what they want to drink (tea, coffee, etc.). The staff forgot to ask. Of course, we understand we could just ask for the drinks, but again, we're paying for higher costs because of the expectation of higher levels of service. In general, I think there are 2 possible issues. Either the staff is not being trained properly, or the person in charge of training has not been performing their job properly. Once again, please take these comments not as being retributional but as providing feedback as to the slowly declining level of service noticeable compared to my previous visits. Customers are paying high prices to stay at your hotel and should expect nothing but the best.

The Hotel is new, and integrated in a huge Hotel Complex. The staff is experienced and friendly. I‘ve got a nice upgrade and as Platinum Member access to Exec.-Lounge, which is really big. Quality of food and beverages at Lounge is delicious combined with a wide range..
